The following table lists the following special LED patterns for the Status, Input, and Output LEDs:
* - The fast blink is nearly instantaneous upon downloading the boot firmware to Flash memory and is, in most cases,
undetectable to the user’s eye.
ICSLAN LEDs
The ICSLAN LEDs light green when there is an active link on the corresponding ICSLAN port. The light toggles off
when a data packet is sent or received.
There are 4 ICSLAN LEDs on the NX-4200. The NX-2200 and NX-3200 each have one ICSLAN LED (see FIG. 7).
FIG. 7 ICSLAN LEDs
SERIAL LEDs
The SERIAL LEDs are two sets of LEDs which light to indicate that the RS-232 ports are transmitting or receiving
RS-232, 422, or 485 data (red = TX, yellow = RX). The light toggles on when a data packet is sent or received.
There are two sets of eight SERIAL LEDs on the NX-3200 and NX-4200. The NX-2200 has two sets of four LEDs. The
NX-1200 has two sets of two LEDs (see FIG. 8).
FIG. 8 SERIAL LEDs
RELAYS LEDs
The RELAYS LEDs light red to indicate that the corresponding relay port is active. The light toggles off when the relay
port is not engaged.
There are eight RELAY LEDs on the NX-3200 and NX-4200. The NX-2200 has four RELAY LEDs (see FIG. 9).
